DSD (Direct Stream Digital) is a one-bit audio format for high-resolution music. The format is based on sigma-delta modulation. Read details about DSD >
I.e. DSD files is a common term, that includes both DFF and DSF audio files.
However, besides these kinds of files, SACD ISO (.iso extension, 1-bit audio ISO) is DSD file too. SACD ISO contains text metadata, that may be extracted during SACD ISO to DSD conversion.
DSF and DFF files are able to contains binary identical audio content.
Sound quality for both file formats is defined by:
- recording, mixing, postproduction/mastering quality;
- conversion quality (read below);
- playback quality (read below).

Sometimes one-bit DSD is considered a more qualitative alternative for multi-bit PCM. However, it is not a simple matter, that is defined by implementation. Read more:
DSD resampling and other processing (even elementary gain changing) lose quality, comparable with PCM resampling. However, it is not a big matter for pro-audio processing.
DSD playback may be implemented two ways:
- Convert to PCM and playback at PCM DAC (digital-to-analog converter),
- Playback directly with DSD DAC.
In general, the second option is preferable. But real result depends on hardware and software implementation.

DFF file doesn't support music metadata (song name, album, performer, artwork) standard way. However, the metadata may be stored in ID3 format in DFF file's chunk (internal data block). For access to the metadata, DFF file player must be able to recognize ID3-chunks.
DSF specification supports the metadata. DSF audio player may have issues with artwork format, size and resolution.
To playback multichannel music at a stereo DSD player, the music sould be downmixed into 2.0 "on fly". Sound quality of downmixing is implementation matter. To save hard disk space, you can pre-downmix music.

Current DSF specification notes raw uncompressed packing only .
From sound quality point of view, for editing DSD files, file format does not matter.

No. DSD has advantages and disadvantages comparing PCM - its competitor.
DSD and FLAC are both audio formats that are designed for audiophile applications. Both ones provide high sound quality in different ways.
